5 Substation Protection & Automation IEC few of the extensions Ed 2.0: Communication networks and systems for power utility automation IEC : Hydro-electric plant communication for control and monitoring IEC : LNs for Distributed Energy Resources IEC xx: Application guides IEC : Communication between substations IEC : condition monitoring IEC : Synchrophasor communication 5

6 Substation Protection & Automation IEC , -13 Standard for Instrument Transformers Part-9 Digital Interface for Instrument Transformers Part-13 Standalone Merging Unit Expected release in IEC Standard for High-voltage switchgear and controlgear Part-3: Digital interfaces based on IEC

7 Substation Protection & Automation IEC High availability automation networks Courtesy: IEEE PSRC H12 WG 7

8 Wide Area Situation Awareness (WASA) 8

9 Wide Area Situation Awareness (WASA) IEEE C Standard for Synchrophasors for Power Systems Extension of IEEE 1344, 1995 IEEE C Standard for Synchrophasor Measurements for Power Systems IEEE C Standard for Synchrophasors Data Transfer for Power Systems 9

10 Wide Area Situation Awareness (WASA) IEC Transmit Synchrophasors information Substation IED IEC PDIF IEC61970 Line Protection GWAP PTRC IEC RMXU TCTR, TVTR XCBR Courtesy: IEC 90-5 WG Topological Node Generator, Line Measurement Control PTRC MMXU IEEE 1588 IEEE C WAMPAC function Power System Angle/Freq. Monitoring Voltage Stability Monitoring Thermal Overload Monitoring State Estimation Real-Time Control Power System Separation Adaptive Protection Wide Area Stabilization { i, v, P, f,.. } Measured Value Synchrophasor Sampled Value 10

11 Wide Area Situation Awareness (WASA) IEEE C (Expected release in 2012) IEEE PSRC WG C5 Guide for Synchronization, Calibration, Testing, and Installation of P for Power System Protection and Control IEEE C (Expected release in 2012) IEEE PSRC WG C4 Guide for Phasor Data Concentrator (PDC) Requirements for Power System Protection, Control, and Monitoring 11

12 Interconnection of DERs IEEE 1547 Standard for Interconnecting Distributed Resources with Electric Power Systems IEC Basic communication structure - Distributed energy resources logical nodes IEC Standard for Wind turbines Part-25, Communications for monitoring and control of wind power plants 12

13 Time Synchronization IRIG-B: External synchronization cable CT -1 CT -2 CT -3 CT -4 CT -5 CT -6 CT -7 CT -8 CB -1 CB -2 TS 1 TS 17 TS VT Line -1 VT TS 2 TS 18 TS ESW-1 Ethernet Switch Network (LAN) ESW-11 TS Line -1 Protection IED-A Line -1 Protection IED-B TS 13

14 Time Synchronization IEEE 1588: Synchronization over data networks IEEE C37.238: Power profile Line -1 CT -1 CT -2 CT -3 CT -4 CT -5 CT -6 CT -7 CT -8 CB -1 CB -2 TS VT VT TS 2 ESW-1 Ethernet Switch Network (LAN) ESW-11 Line -1 Protection IED-A Line -1 Protection IED-B 14

15 Cyber Security IEC Standard for Power systems management and associated information exchange - Data and communications security IEEE 1686 Standard for substation intelligent electronic Devices (IED) cyber security capabilities IEC

16 Other Relevant Standards CIM (Common Information Models) IEC 61970: Standard for Energy management system application program interface (EMS-API) IEC 61968: Standard for Application integration at electric utilities - System interfaces for distribution management 16

17 Major Challenges with Standardization 1. Compatibility with current standards Harmonization 2. Difference in implementation practices worldwide Involvement/demonstration worldwide 3. Interoperability among multiple vendors Broad specifications (flexibility) should be tested among vendors 4. Acceptance from all levels of power utilities More involvement in standardization 5. Gaps in the standardization Proof-of-concept 17
